Razzle, dazzle, foil and frazzle...

[Nik_SpeakerToCats]

Many WW_1 ships were painted with 'Dazzle' cammo patterns to foil surface raiders and U-Boot attacks.

Seems no-one documented their experiments. Or, if they did, reports were lost to time...

So, now that Ukraine has revived the concept to baffle eg Iranian drones, I give you...

World War One dazzle camouflage was not as well understood as it might have been, researchers suggest

That dazzle camo worked with British rangefinders but with the German ones?

Tangential: One of my father's friends had the handy knack of spotting cammo-netted equipment 'in the field'.
He'd reliably call fire on anti-tank guns 'safely' dug in behind eg Normandy hedges.

IIRC, he had odd-coloured eyes.
A chimera, like WIRS' Tim, his L/R eyes saw slightly different colour spectra...

Some of the variants of color blindness works well for spotting camoflaged targets.

Correct. It would work in making ranging hard for coincidence rangefinders, but stadimetric ones weren’t spoofed by it.

Dazzle did however make it difficult to establish course and estimate speed initially.
